Have you not seen that the ships sail in the ocean through the bounty of God so that He may show you the evidence (of His existence). There is evidence (of the truth) in this for every forbearing and grateful one. 31 When a wave covers them like the canopy (of clouds), they call to Allah, offering Him sincere devotion. But when He has delivered them safely to land, there are among them those that halt between (right and wrong). But none reject Our Signs except only a perfidious ungrateful (wretch)! 32 O men, seek protection with your Lord and fear the Day when neither will the father be of any avail to his son, nor will the son be of any avail to his father. God's promise is surely true. So let not worldly life beguile you, nor let the Deceiver deceive you concerning God. 33 Surely Allah is He with Whom is the knowledge of the hour, and He sends down the rain and He knows what is in the wombs; and no one knows what he shall earn on the morrow; and no one knows in what land he shall die; surely Allah is Knowing, Aware. 34
